This is a digital airspeed sensor kit developed and recommended to use for fixed wing frames and VTOL drones in plane mode. This sensor has a very low offset, a high resolution, and, best of all, does not suffer from the noise induced by long cables in analog sensors. All Holybro Autopilot Flight Controller Boards with either Ardupilot & PX4 are supported.
It can be used for detecting stalls and is most helpful in windy conditions. Airspeed requires additional calibration, it may be hard for new users to properly set it up as it may lead to unprecedented behavior unless used and calibrated correctly.
If you use your favorite ground station (MissionPlanner, QGroundControl, etc.) to test whether or not the sensor is functioning correctly, you should be able to see the sensor response. You should be able to see the sensor measured values change if you blow mildly from a distance into the tube (never blow directly into the tube as you will tear the diaphragm — these kinds of sensors have a very sensitive types of diaphragms) or cover it with your finger.
